Art has been shown to have a profound impact on the human brain, enhancing brain function and well-being. Viewing art can activate the limbic system, a part of the brain that mediates emotions and plays a role in visual artistic appreciation. This system is influenced by the artist's emotions and memory, which are reflected in the artwork through specific techniques and choices of images, forms, and colors. While there is no explicit mention of a limbic system in a famous painting, understanding the neurological impact of art provides insight into how artists have learned to engage and evoke emotions in viewers through their creations.

What You'll Learn
Artists use techniques to stimulate the limbic system
Artists have unwittingly been involved in brain and vision research for 40,000 years, according to Dr Patrick Cavanagh of Harvard. Artists use a multitude of techniques to stimulate the limbic system, the part of the brain that mediates emotions. The images and forms chosen by artists stimulate and amplify the brain's response.
Dr V.S. Ramachandran of the Centre for Brain and Cognition at the University of California, San Diego, said artists, either consciously or unconsciously, deploy a range of techniques to stimulate the visual areas of the brain, particularly the limbic system. He describes one technique as the "peak shift effect". This technique has been shown to increase excitement in tests on rats, and Dr Ramachandran believes it explains not only caricatures but all art. For example, a sketch of a nude selectively accentuates the feminine attributes that distinguish it from a male figure.
The discovery of perspective in the Renaissance is another technique that stimulates the limbic system by more closely matching what the eye sees. Early users of this technique often confused the light source and, therefore, where the shadows should fall. This suggested that while the brain readily processed and interpreted line, shadow and shading were less important to our understanding.
The ventromedial prefrontal lobe (VMPFL) is involved in creative cognition, and the dorsolateral prefrontal lobe (DLPFL) in creative output. The VMPFL is influenced by activity from the anterior temporal lobe through the uncinate fasciculus and limbic system pathways. The final visual image formed in the visual brain is then transferred back to the DLPFL and handed over to the motor cortex for execution.
In the visual arts, artists use size, colour, content, symbolic message, material, and context to draw attention to their composition. The degree of attention given to the art may depend on the hormonal levels in the viewer. For example, oxytocin, produced in the hypothalamus, is identified as promoting attachment, bonding, approach-to-others, trust, and positive social behaviour.

The role of the limbic system in art appreciation
Art evokes emotions, and emotions are mostly mediated through the limbic system. This complex network of brain structures plays a central role in processing emotions. When we encounter art that moves us, the amygdala, a key component of the limbic system, can become activated. The activation of the amygdala through the Papez circuit of the limbic system determines the final expression of the emotion.
The limbic system is activated when we view art, and it is responsible for evoking emotions of appreciation, the "Ah" experience. This activation occurs when the image at the visual brain is transferred to the frontal lobe through the superior longitudinal fasciculus (SLF). At the frontal lobe, the image is matched with emotional and memory inputs from the anterior temporal lobe, transmitted through the uncinate fasciculus.
The process of art appreciation involves the activation of the prefrontal cortex, which compares the artwork with similar images and visual scenes previously stored in the memory brain of the anterior temporal lobe. This comparison gives rise to heightened activation in the prefrontal lobe, which then transfers back to the anterior temporal lobe through the uncinate fasciculus, activating the limbic system and evoking emotions of appreciation.
Artists, either consciously or unconsciously, deploy a range of techniques to stimulate the visual areas of the brain, particularly the limbic system. One such technique is the "peak shift effect," which explains how a sketch of a nude selectively accentuates feminine attributes to discriminate it from a male figure. Visual art, such as paintings, engages our visual processing pathways, and the brain processes elements like colour, shape, and spatial relationships to create our perception of the artwork's beauty.

How the limbic system influences artistic production
The limbic system, a complex network of brain structures, plays a pivotal role in emotion processing and artistic production. When artists conceptualize a scene they wish to create, activation occurs in the ventromedial prefrontal lobe (VMPFL), the seat of creative cognition. This activation, forming the visual image in the artist's mind, is influenced by inputs from the hippocampal region of the anterior temporal lobe, which processes memory. Crucially, the VMPFL is also influenced by the artist's emotions, carried from the amygdalo-hippocampal complex—a key component of the limbic system—through the fornicial system of fibres, constituting the limbic system pathway or Papez circuit.
The artist's emotions, mediated through the limbic system, play a significant role in shaping the artistic production. The emotional brain transmits the artist's feelings about the visual scene they intend to create. This emotional input, combined with memory inputs from past experiences, influences the formation of the visual image in the VMPFL. Once the concept of the artwork is formed, information is transferred to the dorsolateral prefrontal lobe (DLPFL) for executive planning. The DLPFL then transfers the concept to the visual brain in the occipital lobe, where the visual image to be painted is formed.
The limbic system's role in processing emotions is central to artistic production, as art itself is a powerful evoker of emotions. Art can elicit a wide range of emotions in viewers, from joy and awe to sadness and nostalgia. It can transport viewers to different times and places, evoke empathy, and inspire reflection on the human condition. This emotional response to art is deeply rooted in the neural processes that underlie our perception of art. When we encounter art that moves us, the amygdala, a key part of the limbic system, can become activated, illustrating the intricate link between art and our emotional brain circuitry.
Additionally, artists themselves may deploy techniques that stimulate the limbic system and evoke emotional responses in viewers. Dr V.S. Ramachandran suggests that artists use techniques like the "peak shift effect," which explains the use of exaggeration in art forms such as caricatures. By selectively accentuating certain attributes, artists may amplify the emotional impact of their work. This understanding of the brain's response to visual stimuli has been utilized by artists throughout history, such as during the Renaissance, when artists began to employ perspective to more closely match the eye's perception.
The intricate interplay between the limbic system and artistic production highlights the complex relationship between brain structures and their functions. By studying the effects of brain damage on artistic creation, neuropsychology and neurology have provided insights into the neural regions associated with art. For instance, the left hemisphere's role in language processing was evident in a writer's diminished artistic productivity following damage to that region. In contrast, a musician and painter with damage to the same area could still create, showcasing the brain's complex and multifaceted involvement in artistic expression.

The impact of art on the limbic system and emotions
Art has a profound impact on our emotions and the limbic system, a complex network of brain structures, plays a central role in this process. When we view a piece of art, our brain undergoes a symphony of activity, integrating emotion, perception, and reward. The limbic system, specifically the amygdala, is activated and this activation is associated with the experience of emotions such as fear, joy, or sadness.
Neuroaesthetics, an interdisciplinary field, examines the specific brain processes involved in viewing and analyzing art, providing insights into why certain artworks or styles evoke particular emotional responses. Art can generate emotional experiences by stimulating the central nervous system (CNS) to innervate the autonomous nervous system (ANS) through the brain stem and spinal cord. This activation of the ANS results in physiological changes in the body, including heart rate variations, reflecting the emotional impact of the artwork.
The impact of art on the limbic system is not a one-way street. Dr V.S. Ramachandran suggests that artists, either consciously or unconsciously, employ techniques to stimulate the limbic system. One such technique is the "peak shift effect," where exaggerating certain features creates a more powerful response. For example, a sketch of a nude figure may selectively accentuate feminine attributes, distinguishing it from a male figure. This principle may explain the appeal of caricatures and the work of artists like Van Gogh and Monet, who could be seen as producing "caricatures in colour."
The emotional impact of art is deeply personal and influenced by individual differences and cultural contexts. Cultural factors, such as the significance of certain symbols or themes, can profoundly shape our interpretation and emotional response to a piece of art. Additionally, our unique life experiences, memories, and perspectives contribute to highly individualized reactions to art.
Art has the power to move us, evoke profound emotions, and even enhance our well-being. By understanding the neuroscience behind art's impact on the limbic system and emotions, we can further explore the therapeutic potential of artistic engagement and its positive influence on mental health, empathy, and cognitive function.

The link between the limbic system and colour perception
While my search did not find any explicit links between the limbic system and colour perception, there is evidence that colour perception is located in the limbic system, the part of the brain that manages functions such as emotional responses and subconscious thoughts. This suggests a strong link between colour perception and the ability to process emotions, learn new things, and increase motivation.
The limbic system is a set of structures in the brain that deal with emotions and memory. It is made up of the amygdala and the hippocampus, which are connected through the fornicial system to the mammillary bodies and then on to the anterior nucleus of the thalamus and the frontal cortex. The limbic system is activated when an artwork is viewed and compared with similar images and visual scenes stored in memory. This activation evokes an emotional response of appreciation.
Colour perception is a complex process that involves the optic nerve, retina, thalamus, visual cortex, and prefrontal cortex. The optic nerve connects the retina at the back of the eye to the thalamus, which processes information from both eyes and sends it to the visual cortex in the occipital lobe. The visual cortex contains cells that detect different kinds of visual information, such as colour, form, and movement, and puts this information together into what we perceive as an image. This image is then sent to the prefrontal cortex, which processes the information along with emotions and memories.
The way we perceive colour is subjective and can be influenced by factors such as lighting, the positioning of colours next to each other, and cultural, temporal, and spatial contexts. Colours can evoke different emotional responses and have different meanings, depending on these factors. For example, studies have shown that cold colours tend to be valued more negatively, while warm colours are more positively received. Artists may deploy techniques to stimulate the limbic system and evoke emotional responses, such as the "peak shift effect", which involves accentuating certain attributes to create a caricature.
